Description
Technical field
It is a kind of spiral reinforcing bar connection with cone cylinder the present invention relates to the reinforcing steel bar connecting device used on buildings
Device and its construction method.
Background technology
Existing reinforcing bar connector is commonly called as grout sleeve, and it increases the intensity of grout sleeve using thicker barrel.But
Be, when barrel is thicker, then the diameter of sleeve must do it is larger, and larger-diameter grout sleeve can not expire in use
Stirrup outer wall outside the building element of sufficient national regulation is away from the concrete thickness requirement between outer wall of the building, and this thickness, which is referred to as, to be protected
Sheath, at least 15 millimeters of the protective layer requirement of plate, wall, at least 20 millimeters of the protective layer thickness of building girder or post is this
The deficiency of grout sleeve is：Because the space in prefabricated components is limited, when longitudinal reinforcement position is constant, on the outside of grout sleeve with
The requirement that protective layer thickness on building element between stirrup can not be up to state standards, therefore, in the concrete of prefabricated components
Longitudinal reinforcement must be moved internally between two parties, to reach the thickness of the protective layer between increase reinforcing bar connector and building element stirrup
It is required that, also therefore still, this will cause longitudinal reinforcement far from the outer wall of prefabricated component, result in the ability of resist torque of wall
Diminish, so that the stress performance reduction of prefabricated components；Meanwhile, when the protective layer in prefabricated components reaches thicker require, then
Longitudinal reinforcement can be caused mobile to centre, the ability of the resist torque of prefabricated components is influenceed；When prefabricated structure reinforcing bar is moved inward,
The ability of resist torque diminishes, therefore, the longitudinal reinforcements of prefabricated components will component both sides it is uniform, it is impossible to concentrate and move to centre
Dynamic, this requires the diameter of grout sleeve to diminish, to meet the longitudinal reinforcement connected on grout sleeve to shifting in the middle of precast wall body
Dynamic distance is as small as possible.However, the aperture of grout sleeve is smaller, grouting amount is lower, causes bonding strength to reduce, and according to state
Family's standard requires that first of horizontal distribution reinforcing bar of shear wall is 50 millimeters away from wall bottom, and still, the height of grout sleeve is typically big
, must be at least provided with together on the outside of the grout sleeve of wall edge member part or shear wall coupling part in 100 millimeters
Horizontal hoop, in this case, when grout sleeve position sets transverse steel again, then transverse steel apart from prefabricated components outer wall compared with
It is narrow, it is impossible to meet the requirement of thickness of concrete cover, occur reinforcing steel bars exposed phenomenon sometimes, cause reinforcing bar easy-to-rust, and can not
Make reinforcing bar and the common stress of concrete, have a strong impact on construction quality；In addition, existing grout sleeve is in use, in order to reach state
Family standard requirement, need in wall additional cracking resistance reinforcing bar, produce crack after preventing concrete component stress, cause construction cost to increase
Height, difficulty of construction increase；The trapezoidal projection of ring-type on grout sleeve inwall is also easy to produce fracture, causes its intensity to be greatly reduced.
The content of the invention
